Abstract
The formulation described herein evolved in the
course of the authors' investigation of possible relationships
between entropy and reliability. What
was required was a measure that, for small networks,
could be easily understood and interpreted and would
be straightforward to calculate, i.e. something akin
to the percentage of demand satisfied at adequate
pressure. A major weakness of the latter is its inability
to handle subnormal service in a satisfactory
way.
It was postulated that the notional net source head to satisfy all network demands would be suitable. A subtle reversal of the roles of normal and subnormal service together with a probabilistic analysis were sufficient to elevate the purely comparative source head measure to a meaningful and accurate reliability measure. Its efficacy is proven by a numerical demonstration. purchase the full-text of this paper (price £20)
